watasi ha, takoyaki yori yakisoba no hou ga suki desu ga, kinou no yatai no takoyaki mo oisikatta desu.

は marks 私 as the topic of the sentence.

So 私は means something like as for me or speaking for myself. It does not just identify the subject in a neutral way; it sets up the speaker’s personal preference.

In this sentence, 私は tells us that the comparison that follows is the speaker’s opinion:

• 私は、たこ焼きより焼きそばのほうが好きです
• As for me, I like yakisoba more than takoyaki

This is a very common comparison pattern:

• A より B のほうが ...
• B is more ... than A

So here:

• たこ焼きより = than takoyaki
• 焼きそばのほうが = yakisoba (more so / rather)
• 好きです = is liked / I like

Together:

• たこ焼きより焼きそばのほうが好きです
• I like yakisoba more than takoyaki

A literal breakdown would be:

• Compared with takoyaki, yakisoba is the preferred one

ほう literally means side, direction, or one of two options. In comparisons, it points to the option that better fits the statement.

So:

• 焼きそばのほうが好きです = I prefer yakisoba / yakisoba is the one I like more

In comparison patterns, A より B のほうが... is often best understood as:

• rather than A, B is more ...

You do not need to translate ほう literally every time. In this structure, it mainly helps express preference or comparison naturally.

In A より B のほうが好きです, が marks the item being singled out in the comparison.

So:

• 焼きそばのほうが好きです means
• it is yakisoba that I like more

This is a standard pattern. Even though 私は already uses は for the overall topic, が can still mark the specific thing that fits the statement.

Very roughly:

• 私は = overall topic: as for me
• 焼きそばのほうが = the thing being identified as the preferred option

In Japanese, 好き is not a normal verb. It is a na-adjective (or adjective-like noun), and it describes something as liked or pleasing.

So:

• 焼きそばが好きです literally feels closer to
• Yakisoba is liked (by me)

But in natural English, we translate it as:

• I like yakisoba

This is why the thing liked is often marked with が.

The が in:

• 好きですが

means but.

Japanese が can connect two clauses, often with a soft contrast:

• ...ですが、...
• ... but ...

Here the contrast is:

• I prefer yakisoba to takoyaki, but yesterday’s festival-stall takoyaki was also delicious

This が is softer than directly saying でも in many contexts. It sounds natural and polite.

Each の links nouns together.

Break it down like this:

• 昨日 = yesterday
• 昨日の = yesterday’s / from yesterday
• 屋台 = food stall / festival stall
• 昨日の屋台 = the stall from yesterday / yesterday’s stall
• 昨日の屋台のたこ焼き = the takoyaki from yesterday’s stall

You can think of の as a very flexible linker meaning things like:

• ’s
• of
• from
• associated with

So the full phrase means:

• the takoyaki from the stall yesterday or more naturally:
• the takoyaki from yesterday’s food stall

も means also or too.

The speaker has just said they prefer yakisoba over takoyaki. Then they add:

• 昨日の屋台のたこ焼きもおいしかったです
• The takoyaki from yesterday’s stall was also delicious

The nuance is:

• Even though I generally prefer yakisoba, that takoyaki was good too

So も helps show that takoyaki still gets positive treatment, despite the earlier comparison.

Because the speaker is talking about a specific takoyaki they ate yesterday.

• おいしいです = is delicious
• おいしかったです = was delicious

Since 昨日 is mentioned, the past tense is the natural choice:

• Yesterday’s stall takoyaki was delicious

It could use でも in some contexts, but が is very common when connecting two clauses in one sentence.

Compare:

• 好きですが、... = I like/prefer ..., but ...
• 好きです。でも、... = I like/prefer ... . But ...

Both can work, but が keeps it as one smooth sentence and often sounds a bit softer or more connected.

No. It only means the speaker prefers yakisoba to takoyaki.

That is an important difference.

• たこ焼きより焼きそばのほうが好きです does not mean
• I hate takoyaki

It just means:

• Between the two, I like yakisoba more

The second half of the sentence makes this especially clear:

• 昨日の屋台のたこ焼きもおいしかったです
• The takoyaki from yesterday’s stall was also delicious

So the speaker likes yakisoba more, but still enjoyed that takoyaki.

Yes, very often.

Japanese frequently omits things that are clear from context. If it is already obvious that the speaker is talking about their own preference, you could simply say:

• たこ焼きより焼きそばのほうが好きですが、昨日の屋台のたこ焼きもおいしかったです。

That would still sound natural.

Including 私は adds a little clarity or emphasis:

• As for me, I prefer yakisoba...

Not grammatically. Japanese commas are more flexible than English commas.

The comma here:

• 私は、たこ焼きより... just adds a pause and can make the sentence easier to read.

The sentence would still be fine without it:

• 私はたこ焼きより焼きそばのほうが好きですが、昨日の屋台のたこ焼きもおいしかったです。

So the comma is mostly about readability and rhythm, not a rule you must translate directly into English grammar.
