Jeffrey's

I like this place. I was able to get a simple burger that fit my dietary requirements but tasted really good. They do country homemade style gluten free buns and they ask you how you like your burger cooked - I went medium rare which was perfect. I also enjoyed the sweet potato fries which were not overly salty like they often are elsewhere. The decor is like a clean version of the stereotypical American diner and the staff were very pleasant. The prices were reasonable for San Mateo. I'll be back soon.

Rave burger doesn't do lunch on weekdays anymore so I hiked over to Jeffrey's for the first time in years No more fixings bar, they put the tomato lettuce etc on for you now, but you can tell them to go heavy on the onion or whatever. There's still sauces like A1 and tabasco there at the back counter Outdoor seating was nice and even though they were busy they were keeping things clean. Good customizable burger. There's wheat and gluten free buns available. I might have to try the burger with pineapple in it next time, but the avocado one was pretty good. They have mushroom too

This was one of the best burgers I ever had. I had the mushroom burger and it was superb. I also had the garlic fries and the strawberry milkshake. The garlic is real garlic and didnt really absorb into the fries so I would just get regular fries and the shake was fresh and tasted high quality. Would def recc. this burger place to anyone wanting a great burger.
