"Delicious breakfast and they serve it ALL day. Great omelettes and they know how to make hash browns with butter instead of canola oil or some other low quality & unhealthy oil. Great service too!"

"Nice and easy breakfast spot. They have plates as well as quick bites - breakfast sandwich, pancakes, etc. Espresso drinks. Lunch & breakfast all day."

"Wonderful hot grilled salmon sandwich with potato salad! Adorable cafe with outdoor seating. The staff has been so friendly to everyone that has come in."

"I have no idea why this place doesn’t have better reviews, but I’m a fan of local eateries that have excellent food! By all means this place is just that! ☺️ I’ve been searching for a decent breakfast spot around Irvine area that would deliver & found no avail, until I found this little gem. Me & my associates are obsessed with many of their items. Their Eggs Benedict, French Toast, & Two Eggs are the go to! Im a fan of French Toast & have not found a place that does it perfect like MUSTARD CAFE! 😍😍😍 I’m trying to work around the menu to try everything and so far it’s been wonderful! Thank you so much for the delicious food! Please keep up the great work! I can’t wait to actually visit this location for breakfast! I love this place!"

"For all your quick fixes, the burgers are awesome. Get some bottomless drinks too"
