Aromatic Grilled Lemongrass Chicken and Crispy Spring Roll Bun Cha The portion is super generous, to say the least. The Bun Cha comes with rice vermicelli noodles, loads of fresh veggies, crispy spring rolls and a lot of grilled chicken. While the chicken is flavoursome, I found the sauce for the noodles a bit bland. Their sate sauce is really good though, so I had most of the noodles with that.
