I would recommend.
Little Sister is located just south of Yonge and Eglinton, and is easily walkable from the Eglinton Subway station. The decor is trendy and you can see the kitchen in the back.
The curries that I had (UDANG KARI - shrimp curry, SEMUR JAVA - braised beef) went very well with the fried rice (NASI GORENG). The cauliflower salad had great flavor and texture contrast. I didn't care too much for the croquettes or the skewers. The cocktails were also quite enjoyable. We ordered 6 dishes and 2 cocktails which came out to ~$50pp after tax and tip.
On service... We were seated near the kitchen where the wait staff seemed to like to congregate and chit chat. One of the topics that night was "what counts as sexual harassment"... which is not necessarily a conversation I want to hear in the background while I'm trying to catch up with a friend. The kitchen staff picked up on this and tried to get them to stop (only after offering their 2c about the subject).
My experience was quite memorable overall - the food was great and I learned a thing or two about sexual harassment legalities.
