I took my out of town friend to Tommy's and she had the soy-peanut butter milk shake. It's great, even if you're not lactose intolerant.
The next time she was back in town, we had her over for a dinner party. We had forgotten some ingredient, and she quickly offered to run out and get it. An hour later, she returned, with some rambling explanation about how she got lost, and the first place didn't have it. Only a year later did she fess up that she actually went to Tommy's to get that milkshake!
Of course, there's lots of other great things about Tommy's. The Meat Pies and Spinach Pies are not really 'pies' in the traditional sense. They take the ingredients and wrap them in dough, then cook them - but it's not like a stromboli. It's super tasty.
