I enjoyed my visit to Firefly Diner where I received very friendly, prompt, courteous service from Lil. The food was terrific, particularly the fresh fruit cup. The owner, Beth, came to our table and we had a delightful chat with her. I look forward to having the opportunity to stop by again for a very pleasant, low key, relaxing meal.
My Mom & I are locals and decided to try Fire Fly Diner for breakfast, and we're glad we did. Stephanie and Beth were very personable and friendly! I had the special Firefly Breakfast Burrito...the best I've ever had! We'll be back soon, it was eggs-cellent!
Our team has sampled many breakfast places over the years, and FireFly's is one of the best. It really rates 6 "mugs" for super large coffee mugs and constant refills. The menu is varied, interesting and reasonably priced. Everyone was very friendly and the owner came over to chat! The ambiance is plain with some variety so the focus is on the food and service.
