The burgers were fresh tasting and delicious! The milkshake was very creamy and thick. The garlic fries were okay- they tasted more like the cheese on top than garlic but were still pretty good. The food came out quick and the staff were friendly and helpful! I’d definitely go back.

Fast, friendly service. The flame grilled burgers are delicious. Plenty of beers on tap. The fried zucchini and mac and cheese are great sides. And of course, the shakes … my oh my. Love this place.

Food was great, tasted very good. The style feels very open and nice. Once you place your order, they will typically give it to you at a table (you get a sign with number). Only complaint is the food is a little more on the expensive side for me. Loved the kids meal for a smaller meal/snack. Comes with main item, fries, and a drink. The burgers are also quite a good size, but on the more expensive side for me.

Wow what a chill, hearty, family friendly restaurant! The burgers and salads blew me away! They serve the most hearty and comforting Americana cuisine in town, hands down! I wish I had more room for the milkshake but I simply couldn't eat another bite after finishing my ribeye salad served in a mixing bowl! No I didn't order for the whole table, it was just for me . And the staff are so attentive and neighborly, felt like I left the bay area and landed in Texas.

My new favorite place! Everything was 10 out of 10! From the staff, service and food! All my food came out fast and Priscilla always made sure to check on us frequently! They have plenty of parking and indoor and outdoor seating as well! I can’t wait to go back and try other items on the menu! Highly recommend this place!

As far as burgers go, Billy Roy's does it right. Tasty with fresh ingredients. I like that they pile the lettuce thick to balance the beef. You can also choose the cook of your patty. Garlic fries were as expected. Good. I didn't try the sliders pictured, but they didn't like it. I suspect they had the wrong expectation though (they didn't like pretzel bun), so don't let that deter you. Also looked fresh to me. Service was great. Plenty of large TVs to watch playoffs. Chill, family-friendly atmosphere. I'm coming back. If you want a delicious, fresh burger instead of that fast food stuff, try Billy Roy's.

Billy Roy's was a nice change from the usual burger joint. And they are so much more than a burger joint. Not just their menu having chicken, tacos, ribs, all ki ds of good stuff. 2nd time visitor and main is it good. Tasty, juicy burgers from local stock (Oakdale). Milkshakes, kid friendly, cocktails, beer on draft and TVs on almost every wall. Indoor, outdoor, bar seating. Man this place is GREAT! So far this is the only location, which is mind blowing since it is incredibly good. I'll be here back and I highly recommend you stop in for some yummy food and drink. A1 food and service.

Was in the area for Business and saw the Reviews and thought I would stop in and try it out. The burger was amazing. It was hard to eat because it had so many toppings. I ordered a half portion of garlic fries and they were unbelievable. It is nice when you order that they have a tray to show you the size of a full portion and a half portion. Would have loved to get an ice cream from their sweets corner but there was just so much food that there was no way to eat anymore. Food came out in rather short order and the person who delivered to the table was very kind. If ever back in the area, I will for sure come back here.
