We've never had a problem getting an inside table, but maybe depends on the day of the week. I'm assuming weekend eves are the most popular, although we last dined there on a Sun eve a few weeks ago, inside.
It's really small restuarant. And not surprising that their indoor seating is already reserved in the summer considering the heat. Just keep trying or if you do sit on their small patio go in the later evening where it's a little cooler out.
