I was at the Coconut Grove area for two weeks as we were roaming around the marina and went four times to Sushi Siam. A little place, on a side street, with very nice waiters and a relaxing and ambience. As we happened to be there in very casual attires, we wanted a place where we could eat good and fresh fast food, served in reasonable time and with a family feel. We almost always had  steamed dumplings and fried soft shell crabs.
