I'm with Paula. Sit at the bar and you can't help but meet people -- if you want to -- or it is ok if you don't chat with anyone, And you can get a soda if you don't drink, that doesn't matter. Experienced this completely by accident when I went to a popular restaurant on a Saturday night while traveling. It would have taken forever to get a table. Had some nice conversations and there is no "alone space" where you feel set apart at a bar, unlike a single table.
