Not bad at all! Tuckers does have gluten free bread options despite the lack of mentioning on their website (only found this out through Uber eats, would recommend them updating their menu online to reflect this).
That said the gluten free bread used was a bit eh... it has an odd smell and taste that definitely impacts the overall taste negatively, otherwise would have been a 4 star, also on the very dense side for GF bread. I know GF bread is SO hard to get right, but sometimes simple options can be a lot better.
Aside from the questionable bread, a little over priced for what it is but taste wise not a bad toastie.
