New Belguim's Belgo may be one of the best beers I've ever had, if not the best. It's a Belgian IPA. If anyone knows another one like it, please let me know.
The Boulevard smokehouse series Collaboration #2 (if you can still find it) is also a Belgian IPA. They may have made it a seasonal though, so not sure if their is any left in town.
Also, the Green Flash "Le Freak" is another that we have at Nespor's:
Beer Advocate: This Belgian Style IPA is an "out of the box" convergence of beer styles where American Imperial IPA meets Belgian Trippel.
From what I've heard, it's a very different take on the style, but a Belgian IPA nonetheless.
