I felt like eating breakfast at lunch time. We went to Denny's near our office and I designed my own "Grand Slam." My hubby had... biscuits & gravy with chicken and we were both very satisfied. Great service and comfort food at a reasonable price. Thumbs upto Denny's on Harbor Blvd. Read more

I am rating this review with 7 Stars. Our Server, Angel, took good care of my wife and I during our visit. We asked for our... table to be wiped. He took care of that without delay. He made sure our refills were topped off and kept checking how weredoing, often. Which is good. Nothing inconvenient ever happened. Thank you Denny?s and Thank you Angel for making our visitenjoyable. We?ll come back again. See you guys soon. ???? Read more
