After reading people's recs (see link below), we decided to go ahead and eat at Sevilla Restaurant last night. I was with my parents and my brother and we shared 3 appetizers and 3 entrees:
Garlic Soup: Egg and garlic soup with four soaked croutons. Good flavor, nice appetizer.
Caldo Gallego: Soup with kale and chorizo. Very good
Mushrooms stuffed with crab: Not that good, mostly just tasted like butter, couldn't really taste crab at all.
Shrimp with Garlic Sauce: A very generous portion of medium sized shrimp in a very garlicky sauce. I enjoyed this, so did my mom! My dad didn't find the shrimps to be very tender or tasty, he prefers the ones my mom cooks at home :)
Seafood with Green Sauce: Another garlicky sauce with clams, mussels, shrimp and scallops. Scallops were not overcooked which was nice. Another generous serving.
Paella Valenciana: Rice with mussels, clams, chorizo, chicken, shrimp, maybe something else too. We didn't get the one with lobster. This was nice, and the portions of each meat/seafood were generous, but it lacked the distinct saffron flavor that should be in paella.
Bread was fine, salads were a bit dismal (lettuce, tomato slice, catalina dressing). Steve R. was right to say that this place is "old line" Spanish food, it seemed like it hasn't changed in years. The entrees were pricey (20 dollars or so) but very large, we probably would have been fine sharing only two. We arrived at 5:45 and they were in "fast mode," so were out of there by 7:00. The place was pretty full the entire time we were there. We had a pitcher of sangria which was fine but nothing special.
Sevilla Restaurant definitely was a good choice for shrimp with garlic sauce, although we may try someplace else (maybe El Quijote) next time. Since I don't live in NYC, I am usually busy eating other (better) things when I am in town so I probably wouldn't go to Sevilla Restaurant again on my own. Still, it's not bad. Thanks again for all the recs
