Help the food critic finish their rather savage review of a trendy new restaurant.
The chef's "deconstructed taco" was visually stunning. I'm still not entirely sure how to eat it, _________________________. _________________________ the artistic presentation was flawless, the actual tortilla tasted like lightly seasoned cardboard. The dessert was surprisingly good. The prices, _________________________, were completely astronomical!
...not entirely sure how to eat it, though. Although the artistic presentation was flawless... The prices, however, were completely astronomical!
Though can be used as an adverb at the very end of a sentence to mean "however" or "nevertheless." This is very common in spoken and informal English. ("Although" cannot be used this way.)
Although is used at the beginning of the dependent clause to introduce the contrast about the presentation.
However is often used as an interrupting adverb in the middle of a sentence to emphasize a contrast. When used this way, it is framed by commas.
