I think Gabriel in Nachalat Shiva (Jerusalem) has to be well up there! We went there a couple of weeks ago and the food and service were absolutely spectacular. I ordered the Tournedos Rossini (medium rare) and it arrived well done, and it was re-done without a murmur. They even left me the big slab of foie gras from the one I sent back to keep me occupied while they did the replacement.

Did you really mean to ask about only glatt kosher places?
