All the classics of breakfast available in vegetarian/vegan form - what's not to love?! Sadie's Diner is a bit of a trek for me but it's well worth the effort. The decor is a bit dingy/eclectic and you might find bits of sand on your seat but embrace it and you'll be just fine.
Someone on here said they found the portion sizes too small but I thought they were very big! My fiance and I shared the breakfast burrito, which was more than enough for the both of us. The coffees also come in gigantic mugs and the waitress was good with refills.
Definitely check this place out if you're in the downtown area!
