Heyyo, I've been there twice and I have no idea why the previous reviews are so negative... Maybe they went during the chaos when they were just having their grand opening? Not sure.. But both of my visits were positive. The first time I had an energetic, friendly and talkative waitress and she was fantastic! Sadly I forgot her name to give her kudos but I did tip well. Her service was great, the food was delicious, the cutlery was clean and the washroom facilities were very clean.
Second visit was much like the first but the waitress was different. Still kind with a pretty smile just not as talkative.. Maybe because it was 6am before I had to rush to the bus depot and we both felt like zombies hahaha. Still, food was still delicious and the service was good.
I'd definitely say Eggs Oasis is rated quite highly. Next time I go for breakfast in Calgary? It's either the buffet at the Kilkenny Bar or Eggs Oasis.
