This review must be taken into context. The context is, that the competing Thai restaurant in the area, Sukho Thai (I also reviewed on this site), is just way better overall.
I found the food at Thai Fusion to be tasty and fresh, but not outstanding. The main issue was with the portions, which looked measured and were noticeably smaller than than at Sukho Thai.
The service was slower as well. And I got the feeling they wanted us to eat and get out quick. It wasn't all that busy though, so I don't know why.
The atmosphere here was like a "3 dressed up as a 9". It was formerly a fast food place, and the attempts to dress it up, fall short for sure. Comparably, dining at Sukho Thai is an experience in atmosphere.
Overall, if compared to other Thai restaurants in the main city of Kelowna, it would compare favorably. But when compared to it's immediate competition in the bedroom community of West Kelowna, it falls way short.
