We've been back to Matt's Big Breakfast quite a few times now and after having had breakfast food at many other places in the valley, I have to update my review to 5-Stars!
I think that if you're a fan of breakfast foods then you'll be a fan of Matt's. My favorite item to get there is the cheese omelette (except I ask for it to be scrambled) with mushrooms, a side of the house potatoes, and sourdough toast. They serve all omelette dishes with 3 eggs so it's definitely a generous portion. Same for the potatoes, you'll get quite a bit of those as well, and they offer you an option of regular hash browns or the house potatoes. The house potatoes have lots of seasoning & taste different with rosemary ... I recommend trying them out! Even the toast tastes great as it's thick cut sourdough, and they serve it with yummy homemade preserves.
The only annoying parts are the parking situation and sometimes the wait time. Parking can sometimes be challenging to find and the wait time can be long if you are part of a large group. Either way, the food makes it all worth it!
