I have only come here for macarons so that is what gets 4 stars. I got a macaron ice cream sandwich (I think taro with cherry Ice cream filling). It was really awesome. I've had a lot of macarons and this is the best in the valley. The macaron itself is perfectly made from a pastry perspective- no crinkles, not hollow, and perfect feet. The ice cream isn't homemade but I didn't expect it to. And for a large macaron at $3.50, not a bad price. I'll definitely be back for that.
As for the pho, I have not had it myself but my family says that it is average but they would not return for the pho.
THat being said, definitely come here for the macaron sandwich. It's crazy that in this ghetto cinderblock looking restaurant, I found the most perfectly delicate and expertly crafted macarons.
