<<Disclaimer: Verify this information before applying it to your situation.>> I can help you with this one! There is a restaurant called Abigael's on Broadway and I believe 38th. It is AMAZING! I mean, absolutely incredible! There are also a few other koshter restaurants around there on Broadway, however I am not sure if they are Glatt Kosher or not. I believe Abigael's has a website (www.Abigael.com). They were so wonderful! I had the salmon and it was absolutely amazing. They also have steak that is in a gf marinade. They have it all here! Even sorbet for desert. Enjoy and let me know if you have any other questions! I am kosher and I never had a problem eating in any NYC glatt kosher restaurants. You can always find something toe at: salads, some soups, simple meat dishes such as hamburgers (not meatballs-they are problematic) many chicken dishes, such as barbecued chicken, grilled chicken, etc. You can have rice, mashed potatoes, etc. I am very sensitive to gluten and rarely have a problem after eating out. Also, Chinese restaurants (tehre are quite a few kosher chinese places in NYC) always have chicken with cashews that is almost always gluten free. And, there are a few Indian places in NYC with many rice based dishes. There is one place on the East Side, Caravan of Dreams, a dairy place that is kosher and that has many many gluten free breads and desserts as well as pancakes etc.Its a great place to eat gluten free. You should have no problem. Enjoy! My wife is Celiac and yet we have been able to eat at various GLATT and non-glatt Kosher restaurants in NYC. What my wife does is to explain to the owner / chief cook / waitress the situation which is then followed by some thoughtful rumination. They usually comeback and say how about one half roast chicken, with vegetables and a baked potato. This does work. If the pastrami can be testified as GF, pastrami on rice cakes is wierd but it also works. The biggest problem is that they may not know if a particular dish is/is no tgluten free. You might look to DININGKOSHER.COM who publish the authoritative guide to kosher new york restaurants as a source. In the end, its a restaurant by restaurant situation. If you are dealing with a few places in a small geographic area then stopping in or calling will probably work. otherwise,start at the As and go through to the Zs....it'll be quite a job. There is a Jewish Celiac Website (the url escapes me at the moment....try google.com to search. The last time I was there they were still nailing the site together. You will problably have more luck with the vegetarian places, the japanese places butyou still must be very careful. It just takes so much time to explain the situation...and having done that they may still not understand and unwittingly """poison""" you. The greatest loss for my wife was not being able to eat barley and mushroom soup out. If we could onluy come up with a gf version of that.....WOW!
