I have friends visiting next weekend, and they are looking forward to a nice upscale dinner when they're here. We were originally thinking of Oleana or Rendezvous. Now, because of other social commitments, it looks like we might have to stay closer to the Allston area. Is there anything in Allston that's on par with those options or close, that could seat a party of 6 on a Saturday night? I have a lot of Allston favorites but nothing really qualifies as "upscale."
