Onyx is a restaurant and café at 70 Alpha Street in the heart of Cambridge. It serves coffee for passers-by and meals for celebrations, and it has function facilities. The website says it is listed as a top attraction on KAYAK's road trip planner for New Zealand. The breakfast menu includes eggs with hollandaise on ciabatta, a sausage and bacon plate, and a spinach and ricotta-style crème fraîche dish with pine nuts, with add-ons such as cold smoked salmon, halloumi and hash browns. Gluten-friendly, dairy-free and vegetarian options are marked on the menus.
The kitchen is closed from 2.30pm to 5.30pm, so plan lunch around that. Ask at reception for the Wi-Fi password. Takeaway and delivery are also available through Uber Eats, with gourmet pizzas, burgers, breads, sides and drinks. Nearby, Open Locally lists four other restaurants within a kilometre. The Gallery and Smoke Collective Barbecue, both about 200 to 500 metres away, have no rating yet. Good Union, 0.4 kilometres away, is rated 4.1 from 659 reviews, and Your Local Espresso and Eats, 0.5 kilometres away, is rated 4.8 from 158 reviews. Our view is that it is a handy place in central Cambridge for a long brunch or a coffee.
