"饭店" can mean both "hotel" or "restaurant", and it depends on where the speaker is from. My impression is that it is more traditionally used for a "hotel" like , usually smaller than a "旅馆". "说" and "讲" can be tricky, and it's best to see what contexts each can or not occur in. 说谎 = to tell a lie. I don't think you would ever use 讲 here. 说明 = to explain (literally, say clear). You would never say 讲明. 说不定 = perhaps/maybe. Hmm. at the moment, I can't think of very good examples which only use 讲, but in time when both 说 and 讲 are interchangeable, 讲 feels a little more colloquial. Examples include: 说话／讲话 = speak/talk 说故事／讲故事 = tell a story 你说什么？／你讲什么？ = What are you saying? Hope this helps! (:

Generally speaking,"讲" and "说" share the same meaning,but still have a little difference: "讲" usually used in oral chinese,and sometimes it means speak by one person without others' opinion on the topic he talked about.For example,"演讲" means one express his opinion on public with many audient,but these audient usually just listen instead of arguing. "说" different from "讲", it always used in written chinese and refers to many people,they are discussing and expressing their different opinions or one express his opinion with others agree with that. "饭店"means restaurant,its main function is to offer the customers food.Ususlly,it do not offer their lodge "宾馆" is different from "饭店",its main function is to offer customer lodge, and offer them breakfast if customer required. "酒店" , its main function is entertainment.It usually offer lunch and supper for some purpose, for example "wedding" "旅馆" is same with "宾馆" in some degree, but it only offer lodge and it is inferior than "宾馆" Above are my understanding for your question,hope it can help you!!

In PR CHINA.... 饭店, 宾馆, 旅馆= almost the same, usually refers to those mid and low class hotel. maybe 2 stars.... However, 饭店 could also means restaurant. 酒店 = hotel, usually refers to those higher class hotels ( 3 stars or above).. In TAIWAN... You have to be careful when you use 酒店 in Taiwan. It DOESN'T refer to hotel. It refers to building places with KTV and with many ladies providing "special service". Also, when you use 饭店, it refers to higher class hotels ( 3 stars or above)..

说 means speak, tell, say, to epress oneself by words 讲 means speak, tell, say, to deliver oneself of 酒店 refer to a large, high level and good-equipped hotel, 宾馆 : its grade is lower or inferior than 酒店， maybe 2 or 3 star. 旅馆 refer to inn or lodge

说 means talk to others, 讲 means talk (especially with explain) almost same meaning, 饭店 means restaurant , 宾馆, 酒店 is almost same meaning as large and deluxe hotel, and 旅馆 means small lodge...
