A literal breakdown is:

• 这家 = this + measure word for establishments
• 饭店 = restaurant
• 的 = linking particle, like of or ’s
• 菜 = dishes / food
• 还真 = really / actually
• 好吃 = tasty / delicious

So the structure is basically:

this restaurant’s dishes really are tasty

A more natural English rendering would be something like The food at this restaurant is really delicious.

家 is a measure word for businesses and establishments such as restaurants, stores, hotels, and companies.

In Chinese, when a demonstrative like 这 or 那 modifies a noun, you usually need a measure word between them. So:

• 这家饭店 = this restaurant
• 那家公司 = that company
• 这家店 = this shop

So 家 here does not mean home/family. It is functioning as a classifier.

的 links 饭店 and 菜, showing a relationship between them. Here it means something like:

• the restaurant’s dishes
• the dishes at the restaurant
• the food from this restaurant

It does not have to indicate strict ownership. In Chinese, 的 is often used simply to connect one noun to another.

Not here.

菜 can mean vegetables in some contexts, but in restaurant contexts it very often means dishes, food items, or the food being served.

So in this sentence, 菜 means the restaurant’s food/dishes, not just vegetables.

Chinese nouns usually do not have special plural marking the way English nouns do. Whether 菜 means dish, dishes, or food is understood from context.

Here, 菜 is naturally understood as a general or collective noun: the food / the dishes at this restaurant.

That is completely normal in Chinese.

Here, 还真 is a spoken expression meaning really, actually, or genuinely. It adds emphasis and often suggests a little pleasant surprise or strong agreement.

So 还真好吃 can feel like:

• really is delicious
• actually pretty tasty
• genuinely good

In this sentence, 还 does not mean still.

Because 好吃 behaves like an adjective in Chinese, and Chinese adjectives can usually serve as the predicate by themselves.

So:

• 菜好吃 = the dishes are tasty
• 他很忙 = he is busy
• 今天很冷 = today is cold

In basic descriptive sentences like this, you normally do not use 是 before an adjective.

It is best understood as a stative adjective in Chinese grammar.

English learners sometimes think of it as to be tasty, but in Chinese it works more like an adjective such as delicious or tasty. That is why it can directly follow the subject without 是.

So 菜好吃 is a normal adjective-style sentence in Chinese.

Not always.

饭店 often means restaurant, especially in everyday speech. But depending on region and context, it can also refer to a hotel, especially in formal names.

In this sentence, because we are talking about 菜 being tasty, the meaning restaurant is clearly the correct one.

A very common alternative word for restaurant is 餐厅.

Yes, people would understand it, but 这家饭店 is more natural and idiomatic.

When talking about a restaurant as an establishment, Chinese usually prefers the measure word 家:

• 这家饭店 = natural
• 这个饭店 = understandable, but less standard

So learners should generally use 这家饭店.

很 is a neutral degree word, often just meaning quite or serving as a natural linker before adjectives.

还真 sounds more expressive. It often suggests that the speaker is impressed, pleasantly surprised, or strongly convinced.

Compare:

• 这家饭店的菜很好吃。 = The food at this restaurant is tasty.
• 这家饭店的菜还真好吃。 = The food at this restaurant really is delicious.

So 还真 gives the sentence more personality and emphasis.
