Breakfast buffet in Lisbon?

I guess it depends on the hotel. We stayed at the hotel Lisboa and had their breakfast buffet, it was fine nothing more.

Probably not to the extent you are thinking, where non-guests go there for breakfast, and it is sort of a luxury spread. Breakfast itself is not much of an affair in most of Europe, Hotels serve it as a service to guests, many can be good, but not worth the effort to go there and pay what is typically a hefty price if not included in the room price.

If you are still interested, I would look into the higher end hotels that are part of a chain with lots of business clientele.

Most hotels offer a breakfast for guests. With some it’s more continental style with bread of some type and juices, coffee, etc. Many offer a buffet that has cooked foods, lunch meats, cheeses, yogurts, cereals, breads, fruit, juices, coffee, etc. Buffets can vary greatly between hotels with regard to the cooked foods, and variety of meats and cheeses. The better hotels will generally have a better buffet and it will cost more (20-22€). More budget friendly hotels will have less of a selection and the breakfast will either be included with the room price or for a nominal amount (9-13€). When selecting a hotel we’ll look for breakfast photos to see if it’s worth it.

Thank you all for your replies. @Paul, yes you're right that I am thinking of the kind of luxury breakfast buffet where non-clients of a hotel go to. Interestingly, where I grew up in Africa, luxury breakfast buffets were offered by the few European hotels that dotted the capital, such as Novotel, Golden Tulip, and a few local hotels like Labadi (I think that one is government owned). European expats went to enjoy those breakfasts too from time to time.
