Things to do in Plymouth on a Budget

Despite having lived in the UK all my life, I haven't actually travelled much around our little island. This is something I really want to change in the next couple of years. My sister is currently studying at university in Plymouth, and my boyfriend knows just how much I miss her, so a couple of weeks ago we made the four hour trek down there to stay for a few days. Whilst he drove I provided the entertainment of shouting 'road trip, road trip' every few minutes, and making up my own lyrics to songs on Radio One (a standard long journey process for us). 
As we're both currently job hunting and saving for a flat, we really didn't have much cash to spend, and thankfully, we really didn't need to. We stayed for four days and spent hardly anything, despite drinking on a couple of nights and going out for dinner. The first evening we hit up Revolution Bar, and had some awesome cocktails and surprisingly really tasty food. I posted a whole review of it a couple of weeks ago. Side note: if you go, get the nachos - they have vodka salsa and it's really damn tasty. This was a great place to go to enjoy a nice atmosphere and yummy food and drinks without a massive price tag.
The best thing to do when you're low on money and visiting Plymouth is definitely to go to the Hoe and the Barbican. The Hoe is not only glorious because you get to take pictures with road names like 'Hoe Approach', but because it's basically the main seafront-y area. Plymouth doesn't really have a formal beach (correct me if I'm wrong), and this is really where the centre of everything is. it's got the awesome lighthouse as well, which you can go up if you pay a couple of pounds. We opted not to do this, and instead we bought some picnic bits, and sat in the sunshine to eat a (slightly hungover), but really picturesque lunch together. 
Next up was the standard night out. We honestly probably spent about a tenner each on this (including food) after pre-drinks, aka it was my kind of night out! As my sister is a first year student, we hit up all of the bars near her that turned into clubs later on in the night and had a whirl. The best part of the night? The fact that there was a cafe called Caffeine Club open 24/7. I mean, guys, I GOT NACHOS AT 4AM. The town I live in has nowhere open at 4am for food, let alone somewhere that will actually serve you food on a plate. I was basically in Steph food paradise, and the price of the food at Caffeine Club is astounding. Plus, for all you tea lovers out there, you can walk in at any time of day or night and get a pint of tea.
Anyway, these were basically my favourite parts of heading to Plymouth for a few days on a budget. let me know in the comments what you would include!
