Situated on a block of many ethnic restaurants in Allston, Ma., Carlo's is a small, very popular restaurant with a delicious menu. Late in the evening, you will find a long line but it is worth the wait. From the Antipasto to the pasta to the Entrees there are few things on the menu you will not want to try. I always have the shrimp appetizer but each time a different dinner. The service is great even though it is very busy and the tables are extremely close together. Give it a try and you will, like me, add it to you dining rotation.
