Matahari Grill gets a 3.5 for me. I've been here a couple of times, a few years apart but I definitely intend on returning much sooner. My first time dining here was at lunch on a weekday and second was during dinner. Both were very different experiences ambiance and service-wise. Service at lunch was fast as it was busy. Dinner service (it was a Friday night) was rather slow, though we were there for a special occasion and rather enjoyed the low lighting the relaxed vibe. Definitely though, there is a lack of consistency with the level of service.
As for the food, I've enjoyed pretty much everything I have ever ordered here. I've had their spicy eggplant appetizer and their famous beef rendang during both visits and both times have enjoyed them immensely. I'm a creature of habit and have a difficult time veering from menu favourites but have made a conscious effort to try some of the other menu items next time. While the crepe dessert is so-so. it's hard to pass up as the sweet pandan leaf flavour nicely rounds out your meal.
Matahari ranks as a fave for me when it comes to restaurants that serve South East Asian cuisine here in Toronto (not that my list is very extensive though, to begin with). If their service improved, I'd definitely be there more often and recommending it a bit more to friends.
