Remembering trips to greek taverns, they were still using benches and earthenware beakers in the twentieth century - however, that might have been partly to conceal what they were putting into them. Previous to the roman empire, as far as I can tell, glass was a phonecian speciality, coming (mainly) from Lebanon. It was also very expensive, and will have been considerably more fragile than nowadays. Pottery, even glazed, was widely available, and, one imagines, considerably cheaper, and metal beakers were probably used because of their hard wearingness, since, with the metals available, I'd bet heavily on them adding a certain flavour to the beverage. They can't have been that cheap either, considering how much work is required to beat out a metal goblet. Leather jacks, waterproofed with pitch (that doesn't sound too gustitavely attractive, either) from that sort of period have been found further north, and possibly were used in greece as well, but haven't happened to survive - or possibly I just missed them. For travellers, soldiers and the like it seems a good solution - and these are exactly the people who'd transport the tecnology fastest.
So, no, unless it was a very posh tavern, I would expect earthenware, or served from the amphora into your personal jack (so you'd know where it had been, even if not what had gone into it.
About chairs, unfortunately, I am ignorant.
