Based on the other reviews I've read, it appears we should have tried the roast beef. Instead we had the shrimp basket and it was average at best. It seemed to take quite awhile to prepare for a fast food place. The location across from the beach is nice though and allows for a leisurely walk before or after. The prices are reasonable. Based on the other superb options Boston offers (ex. Italian Express Pizzeria), I would only recommend Kelly's if you want a quicker stop and your primary aim is to be near the beach (or, you take the advice of others and try the roast beef). Otherwise, I'd go elsewhere.
