יש לך המלצה טובה למסעדה ליד הים?

Literally, יש means there is / there are, and לך means to you. So יש לך literally means there is to you.

That is the normal Hebrew way to express possession, so in natural English it becomes you have. In this sentence, with question intonation, it means Do you have ...?

Hebrew usually does not use a helper verb like English do in questions.

So a statement and a yes/no question can have the same word order:

• יש לך המלצה טובה... = You have a good recommendation...
• יש לך המלצה טובה...? = Do you have a good recommendation...?

In speech, intonation does the job, and in writing the question mark helps. In more formal Hebrew, you can add האם at the beginning:

• האם יש לך המלצה טובה למסעדה ליד הים?

לך is the preposition ל־ meaning to, plus a pronoun ending meaning you.

So:

• לי = to me
• לך = to you
• לו = to him
• לה = to her

A useful detail: לך is spelled the same for masculine and feminine singular, but the pronunciation changes:

• to a man: lekha / lecha
• to a woman: lakh

So this sentence can be said to either one man or one woman.

Because המלצה is a feminine singular noun, and Hebrew adjectives must agree with the noun they describe in gender and number.

So:

• טוב = good, masculine singular
• טובה = good, feminine singular

That gives:

• המלצה טובה = a good recommendation

Hebrew has no indefinite article. There is no separate word for a or an.

So:

• המלצה can mean a recommendation
• מסעדה can mean a restaurant

Hebrew does mark the with ה־:

• ים = sea
• הים = the sea

So the sentence has no word for a, because Hebrew simply does not use one.

למסעדה contains the prefix ל־, which usually means to or for, attached directly to מסעדה (restaurant).

So here it means for a restaurant.

Hebrew often attaches short prepositions directly to the following word, especially:

• ב־ = in
• ל־ = to/for
• כ־ = as/like

So instead of writing them separately, Hebrew normally writes them as one word.

Yes — in normal unpointed Hebrew spelling, למסעדה can represent either:

• for/to a restaurant
• to the restaurant

Context tells you which one is meant.

In this sentence, the intended meaning is clearly for a restaurant, because the whole sentence is asking for a restaurant recommendation, not talking about going to a specific restaurant.

ליד means near / next to / by, and הים means the sea.

So:

• ליד הים = near the sea / by the sea

In this context, Hebrew naturally uses the definite form the sea, just as English usually says by the sea or near the sea, not near sea.

In this sentence, טובה most naturally describes המלצה, because it comes directly after it:

• המלצה טובה = a good recommendation

So the sentence means Do you have a good recommendation for a restaurant near the sea?

If you wanted to say Do you have a recommendation for a good restaurant near the sea?, a clearer version would be:

• יש לך המלצה למסעדה טובה ליד הים?

Yes. Both can be understood, but the nuance is a little different.

• המלצה על מסעדה often means a recommendation about a restaurant and is very common in everyday Hebrew.
• המלצה למסעדה can sound more like a recommendation for a restaurant, especially when someone is looking for one.

So the sentence you have is understandable, but learners will also often hear:

• יש לך המלצה על מסעדה ליד הים?

Both are useful to know.
