I visited Brillobox for my second time a couple weeks back. My friend and I were on a monster road trip and we stopped in for dinner on one of our nights in town. We got there around 9:30-10 and walked into a night of pub quiz. We did not participate, but the music they were playing along with it was pretty great ("Gilrs on Film" by Duran Duran and "Cool It Now" by New Edition are 2 examples).
I had a pretty tasty hamburger and my friend had the bbq beef. Hw seemed happy with it. The waiter was attentive and we had a 2nd round of drinks pretty quickly.
I'm particularly fond of the decor of the bar, all red, flocked wallpaper and ravens here and there. The first time I went, it was much less crowded and I was able to get a cushy booth. This time, it was bar stools, which was fine.
The crowd was a bit younger and more hipster than I remembered. This isn't a judgement or points against the place, just an observation.
All in all, I'd recommend Brillobox. The food is tasty and pretty cheap, the atmosphere is groovy, and the crowd is fairly accomodating.
