Thanks for the replies so far. I'm looking to try some new places on our next trip and not plan the usual table service meals. TG looks like a nice out of the way place to sit and have drinks and a leisurely meal. If we go next summer, my DD will be 12 and she won't need to be entertained by the surroundings. She's already mature enough to enjoy dining at a finer restaurant.
Since it is walk up, is it usually busy and a long wait to get seated?
