Candela is a nice spot for dinner with decent food. I actually had better service at the bar than we did from our waitress at dinner, and will probably only go back for drinks. Definitely go for happy hour - they have good deals, and if you want to splurge, try the Mojito. Yum.
As for dinner, I had the spicy shrimp pasta dish which was good but almost too spicy. We were offered coffee to end the meal but then out waitress disappeared before we ever got it. We decided that a stop at Dunkin Donuts was a better use of time and money than waiting for her to come back with the coffee. My date had the lobster ravioli, but he was more impressed with it than I was.
Candela is light exclusively by candles so it's cool for ambiance, but if you're looking for spectacular food and service, you should probably go elsewhere. If you're looking for a nice place to start your night with a drink at the bar however, this is the place.
