I haven't spent much time at RiRa's for late-night drinking, mostly because of its reputation for being crowded. But I had an awesome, nap-inducing dinner there one night.
My friend and I had done an afternoon fundraiser/bar crawl one day and we were starving afterward. We headed to RiRa's at around 5 pm, before any of the crowds got there, and we were seated upstairs. We were the only people up there for most of our meal. Had we been on a date, the candle-lit atmosphere would have been awesome. I had the beef and Guiness stew. It was heavy and so so delicious. So my point is that if RiRa's doesn't suit you as a bar, definitely try the food during a less-busy time. It's well worth it.
