I went last year solo for the first time (although I'm a regular at DL solo) and had a great time. At the time I had booked:
Chefs de France, T-Rex, Crystal Palace, H&V, San Angel Inn, Y&Y, Sci-Fi
I never felt awkward at any of them, and my waiters (yes, all male, I don't know how that happened...) went out of their way to make me feel welcome and chatted with me a bit. CP and H&V were my first character meals, and while they were fun, I have no interest in them this year.
So far for this year, I have:
T-Rex, Y&Y, San Angel Inn, LTT, H&V (dinner), Chefs, Boma, Kona Cafe
Most are repeats, so they must have been good!
