Other than a few spots on Montague Street, Brooklyn Heights ain’t exactly overflowing with enticing al fresco dining options. A relatively recent newcomer to the northern stretch of Henry Street is looking to get in on the sidewalk action though: Uncommon Grounds, which closed in August for renovations (including the addition of a full kitchen), is looking to add seven small outdoor tables along Cranberry Street, and will be pitching the idea in a public hearing before Community Board 2 tonight. In general, we’re big fans of sidewalk seating and can’t see any reason why permission wouldn’t be granted. Can you? GMAP
