  I've seen some reviews on the curry being watery, but I don't think it's THAT thin. It's almost like a squash soup consistency. It's not so thin that it's literally like water, but it's not thick like an Indian curry. It's a medium consistency. I really like the yellow curry and the pumpkin curry. I think they're delicious! But, everyone has different pallets. I think the flavors are good, but that's just me.
  
  The Fried Sweet Potatoes Are DELICIOUS!
  *drools*
  
  The reason I am kicking down a star isn't because of the food being gross or anything, it's because they are pricey.
  Their price to portion doesn't make sense.
  
  The establishment itself is kind of in the ghetto and the building itself is a little run down looking.
  It's always HOT in there!
  It's clean, but small and a little "dank" feeling.
  
  If you feel like you have a little extra money to burn, the curry is REALLY good, just expensive.
  AND.. This is the ONLY place in town that has single serve BROWN RICE!

  Stopped here while on a road trip. I had wanted thai and read rave reviews.
  
  My husband and I weren't sure what to expect of Midwest Thai food, so we decided to play it safe and go with our tried and true dishes - Pad Thai and Green Curry. We ordered takeout and they never asked what spice level I wanted. Based on my other Midwest observations I assumed the spice level would be low and that was true.
  
  The curry was very watery and had only green vegetables which was strange to me. The pad thai was bland and dry - it needed more sauce.
  
  I don't think I'll ever find myself in Sioux City again, but if I do I will find somewhere else for dinner.

  I was really looking forward to this place, but I hate to say that I've definitely had better.
  
  I ordered the duck curry and the pad Thai. The pad Thai was good, but lacked spice. There wasn't anything bad about it, but it wasn't a standout either. The noodles were also a bit hard.
  
  The duck curry was a bit too watery for me and barely had any duck in it. Again, this dish was crying out for some spice and needed to be way thicker. The curry flavor was quite muted and one of the weaker ones I've had. The one part that really bothered me besides the missing duck meat was the use of canned pineapples. This should be a crime against humanity for Thai restaurants. It was quite off-putting especially when the food isn't cheap.
  
  Perhaps my expectations were too high, but I was a bit disappointed with the food. The flavors felt like they were very watered down to meet American palates and didn't taste authentically Thai.

  Awful, overpriced, watery panang, so watery that when it arrived at my table I asked "are you sure this if panang??" Possibly worst panang I've ever had. The rice was pretty good. $15 minimum for cards/debit. Not a fan.

  I would give this restaurant 3.5 stars.
  This is my second time checking this place out. The first time I came, I waited to be seated for about 5 mins. Nobody greeted me and in the end, I just sat myself. I got the Thai beef noodle which was okay. It's similar to pho but did not really taste like it. It was a good portion size but I probably would not re-order it again.
  
  The second time I came, I was seated very quickly. I ordered the pumpkin curry with sticky rice. As an appetizer, I had the Golden bags. The golden bags were very crispy, very buttery and was filled with cream cheese.
  
  I was expecting the pumpkin curry to be flavored pumpkin but it wasn't. It also wasn't your typical creamy curry texture. It was watery like a soup consistency which had zucchini and kabocha pumpkin in it. It tasted more like a red curry than anything pumpkin flavored.  But it tasted pretty good with a good amount of coconut.
  The sticky rice was dry and seemed like it was under cooked. It didn't seem like it was freshly cooked, but more like it was a packaged/microwaved instant type.
  But this place seems like it's the only Thai restaurant around so I may come back to try some more of their dishes. I hear that their noodles and rice dishes are yummy!
