I was skeptical when I noticed a new restaurant had taken over the old KFC location, but was pleasantly surprised when I had the chance to stop in when looking for dinner on short notice. I had my meal at dinner on new year's eve before heading out for the night so the restaurant was empty, though I do notice regular flow of customers around dinner time on my way home from work.
Looking at the menu I noticed some similarity to items you'd find at Swiss Chalet so I chose to do a somewhat of a comparison. I ordered a white meat 1/4 chicken dinner with a poutine side. The meal came within a short amount of time and was nice and warm.
The particular things I liked about my meal were that the fries were really good. They were very crispy and didn't get super soggy under the poutine's gravy. Additionally, while Swiss Chalet cooks their chickens in a rotisserie, Golden Swiss barbecues their chickens and the sauce they use had just the right amount of sweetness and tang to it. Finally, I must comment on the service. The owner, who served me, was very warm and welcoming and attended to my order promptly. Every interaction he made with me, he had a smile on his face and even said he'd accommodate my early work schedule so I could grab breakfast since I most enjoy American diner style breakfasts.
At the end of the day I would say I was quite content with my visit and I would for sure make a return visit. The only disadvantage I see for Golden Swiss is being tucked away on Neilson and not prominently on display to passersby.
