Paterisserie La Ruche is always on the way between the Plateau and downtown.
Food: It's literally perfect for everything from a quick Americano or latte to a little sweet treat or a full-on lunch (Sandwiches, salads, quiches and soups). I've tried almost all the lunch options they have and my favourite is their quiches. They're perfectly individual sized and super satisfying flavour combinations like leek and goat cheese. For desserts, I haven't tried all of them but the individual black forest is a favourite of mine. For pastries, their croissants are amazing. They also have a short but varied brunch menu.
Vibes: All the staff there is really helpful - They make you feel very comfortable and check up on you which is more rare at a cafe.
Decor: Really vibrant garden decor with yellow metal furniture and real plants. Their picnic tables seems to have warped over time and make it a realllly awkward place to sit but it is one of the only options if you have a group of 4.
The ONLY small downside: Recently they removed their Wifi because they were having trouble keeping it under control. It's too bad because it's the perfect place to study if you want somewhere with good coffee as well as food.
