I had the anytime burger and it was amazing. You can't go wrong with an egg on a burger.
Brightside has tons of televisions and projectors which makes it unique for a breakfast or lunch spot, they play a lot of the UFC fights and sporting events so it's a great alternative to places like Buffalo Wild Wings to watch an event, plus its downtown so after the game or fight, you can hang out around downtown and take in all the fun around Fremont street.
I'd recommend Brightside cafe for a quick bite to eat or a fun place to watch a sporting event.
