We tried out Blast Burger for lunch. The restaurant was 2/3s full at 1pm on a Sunday. We easily found a seat and placed our orders within 5 minutes. The Blast Burger with jalapenos several ways was excellent. My husband inhaled the Philly cheese special. We both had the onion rings and agreed it was worth the surcharge. The burger was similar to 5 Guys. I rank Blast Burger over 5 Guys for the following reasons: non burger options on the menu, daily specials, space themed dinning room, beer menu and great outdoor seating on the Lake Oswego promenade.
