A friend is in town for business, and I'm hoping to meet him for dinner near his Union Square hotel. Apparently, the place is teeming with suits for some big biotech meeting, so we're looking for a place that might not look great or have a lot of buzz, but just has good food and a friendly atmosphere. Being Monday, the problem is compounded by many places being closed. Any help in this last minute request would be greatly appreciated. We can certainly hoof it out of the area to open up more possibilities, but we'd prefer to walk instead of hoping on Muni or taking a cab.
