The best restaurants serving Thai food in Dundonald Merton London

We first had their food dine in and it was amazing. But tonight, we had it delivered. It is the worst £70 dinner I spent. Ordered prawn pad thai, tamarind duck stir fry, minced chicken larb, beef sirloin phad sieyu. Pad thai looked pale, had 3 pcs of prawn. It was very bland, looked more like a soup dish than a wok fried noodle dish from how soggy it was. The noodles tasted boiled as well. It was just sweet. No sour notes. Just sweet. Tamarind duck had leaked its sauce from the package. Duck was very rubbery, veggies tasted raw. Also, just very sweet. It's described as having sour lime flavour. None of that came through. Larb tasted like a gamey chicken mince, no salty or sour flavor as expected from a Larb. You can only taste tons of black pepper, red pepper spiciness, and the raw thick sliced red onions. Lastly the beef noodles, phad sieyu. This we paid extra £3 for the sirloin. It came very dull, bland, almost tasteless, no wok/stir fried flavor. The beef was also rubbery and had no discernible seasoning. This also had broccoli, cauliflowers, chunky carrots which was not necessary for a phad sieyu. Also, just overall greasy and sweet, nothing else. I am truly disappointed with the quality of the food considering we had enjoyed dining in more than 4x in the past months here. I hope this was a one off thing because they were much much much better before.
