I joined Happy Cow so I could post this, since the only review is from 2008.
Flow is not a vegan restaurant, but they will prepare you the best vegan meals you can find, upon request, especially if you call them in advance and make reservations. The chef enjoys coming up with different dishes and is truly passionate about his craft, and it shows in the food. Jim Thorpe is about an hour away from me, but I'm going there for my wedding anniversary in a few weeks for a nice vegan dinner at Flow.
Chef Zachary Pelliccio, who took over a couple of years ago, is a fantastic chef whose vegan dishes are at least as good as any other dishes I've tasted, and better than most. I've been to Horizons, Vedge, Candle 79, Sprig & Vine, etc, so I've had excellent vegan food to compare it with.
I've had the pleasure of going to two separate vegan events he organized at Flow, and was blown away. One was a 10-course vegan tasting menu, the other a 7-course vegan dinner. Both were amazing, made with seasonal produce and without using any "meat substitutes" like tofu or seitan. I can't praise him highly enough. I'd give them 5 stars but Happy Cow won't allow it since it's not a vegan restaurant.
